    This study explains how qualitative content analysis was applied to investigate natural hazards in textbooks for children with intellectual disabilities in Iran. Qualitative content analysis of textbooks is one of the ways for understanding the priorities of Iranian education system with regard to natural hazards. Data samples included whole textbooks for children with intellectual disabilities in all grades during school year 2020-2021 in Iran. Data were collected by transferring textbooks to MAXQDA 2018 software and coding themes with the software. A narrative format was used for analyzing qualitative data. Examples were presented along with tables and quotations in the study. Peer checking and expert check were employed to ensure trustworthiness of the study. The above research design showed the strengths and weaknesses of information provided in Iranian textbooks on natural hazards and disasters management. Iran is a disaster-prone country and various natural hazards happen in Iran every year including earthquake, flood, drought, and extreme weather. Children are a vulnerable population in disasters. One of the most important issues for children's health is disaster preparedness. Intersection of age with other social determinants such as disability, gender, and ethnicity can increase vulnerability. This method was recommended to researchers investigating representation of natural hazards in textbooks of children in different countries, grades, and textbooks. Furthermore, it is possible to use this method for a comparative analysis of information in two or more countries, or different school years in a country. • Explicit and implicit information on natural hazards in textbooks could be investigated with qualitative content analysis. • This method could facilitate cross-country comparisons by providing a framework to investigate the content of textbooks for children without disabilities and/or with disabilities. • It is a valuable method for evaluation of disaster programs for children in local, national, and global levels

    Preparing children for climate related disasters

    Climate-related disasters affect different dimensions of children’s health and well-being both directly and indirectly. Reducing children’s vulnerability and exposure to climate-related disasters is crucial to protect them against risks. Children as climate-change agents and future leaders at local, national and international level can obviously contribute to reduce vulnerabilities in families and communities and transfer knowledge to them. Moreover, children can advocate for climate change mitigation. In the long term, participation of children in the climate change mitigation programmes may lead to fewer disasters and, consequently, less risk to their health. As government policies have failed to fully address and respond to the drivers of climate-related disasters, disasters preparedness and education for children should be considered an essential activity to protect children from disaster’s risks. Main factors in shaping children’s behaviour and response to disaster are increasing the risk perception and knowledge of the children. When a child perceived likelihood, susceptibility and severity of a disaster (such as earthquake), then they would be able and willing to learn how to prepare for that. So far, disaster education programmes for children have mostly relied on offline school-based training. Different innovative approaches can be applied to continue education within online and digital formats including virtual reality, digital games and online platforms. However, an advocacy support by influential entities such as companies engaged in entertainment industry is required to raise the awareness of public and particularly the children about disaster preparedness

    Mill. is one of the most endangered tree species in Iran where it is represented by small fragmented populations in the north of the country. 18 simple sequence repeat (SSR) loci (10 nuclear and 8 chloroplastic) were used to evaluate the genetic diversity and population structure of from the Hyrcanian forest. For nuclear SSR, the number of alleles detected per locus ranged from 1 to 5 and observed heterozygosity (H) was between 0.125 and 1.000. Analysis of molecular variance (AMOVA) indicated a high level of variation within populations (84%) and low levels between populations (16%). Based on structure analysis, the four studied populations were divided into two main clusters that have genetic distance Fâ=â0.3. The Shafaroud population was separated in the first cluster, Siyahmazgi, Qalehroudkhan and Veysroud were placed in the second cluster. The UPGMA analysis confirmed the results of Structure analysis, separating the Shafaroud population from the others. The 8 chloroplast SSR loci used to screen the populations showed no polymorphism. In General, low nuclear genetic diversity, no polymorphism in cpDNA and considerable genetic differentiation among populations in short geographical distance represent a serious genetic erosion threat for in the Hyrcanian forest, even hinting at an ongoing extinction vortex. Therefore, due to significant decline in genetic diversity, it is essential to introduce constraints protection upon the areas of distribution of all four populations of this species in Iran.Castanea sativaC. sativaOstC. sativ

    Phylogenetics and Biogeography of Lilium ledebourii from the Hyrcanian Forest

    ilium ledebourii (Baker) Boiss is one of the most endangered lilies, restricted to only a few small and fragmented areas in the Hyrcanian forest. This study aimed at evaluating the taxonomy of this unique Iranian lily and reconstructing divergence time from other species of the genus Lilium to address the role of this region in its diversification. Phylogenetic trees based on nuclear ITS and chloroplastic matK strongly supported the monophyly of the genus Lilium and division into subclades hardly matching prior morphological classifications. Biogeographic analyses using S-DIVA revealed East Asia as the ancestral range from where Lilium presented a multidirectional expansion towards North America, West-Central Asia, North Asia, and Europe. Diverging from ancestral Lilium during the beginning of Eocene (50 Ma; 95% HDP: 68.8–36.8). Specific members of Lilium colonized Iran (Western Asia) separated from the Clade IV (West-Central Asia and Europe lineage), and then yielded the Iranian L.ledebourri. Accordingly, the north of Iran appears to have promoted both long-term persistence and migration of Lily species from Asia to the Europe

    Representation of Disasters in School Textbooks for Children with Intellectual Disabilities in Iran:A qualitative Content Analysis

    School textbooks are one of the main sources for teaching and learning in an education system. This study aims to investigate the representation of disasters in school textbooks for the children with intellectual disabilities (ID) in the education system in Iran. This study uses a qualitative content analysis method. All school textbooks for students with ID in the education year 2019-2020 in Iran were collected. Among the whole 164 textbooks, 18 had content about hazards. Data were analyzed qualitatively by MAXQDA 2018 software. Textbooks in most grades cover the topic of disasters triggered by natural hazards including geophysical (earthquakes), hydrological (floods), climatological (extreme temperatures, and drought), meteorological (storms/wave surges) and biological (epidemics and insect/animal plagues). Moreover, there are various topics of disaster risk management in the textbooks including mitigation, preparedness, and response. Natural hazards are well covered in school textbooks for students with ID in Iran. However, more content about sheltering in disasters, reunification, as well as disasters’ response and recovery will help children with ID in Iran to perform better during and after disasters. Moreover, the textbooks in several grades provide some debates on the prevention and the spread of infectious diseases for preparedness against epidemics. The COVID-19 pandemic and the significance of preparedness of vulnerable groups against pandemics evidence that school textbooks are a key means to transfer the information of preparedness in emergencies of all sorts to all children including children with ID

    Objective: School textbooks have a significant role in transferring knowledge to the students and changing their behavior. This work aims to analyze school textbooks to find the representation of natural hazards in Iran, which is vital for supporting children in disaster situations. Methods: In this study, a qualitative content analysis was used. Data were analyzed qualitatively by using MAXQDA 2018 software. For the 2019–2020 school year, 300 Iranian school textbooks in Persian language were collected. Results: Findings of this work show that students receive information about disaster risk reduction (DRR) education through the primary and secondary grade levels in all 12 grades. The educational content covers various types of natural hazards, including geophysical, hydrological, climatological, meteorological, and biological disasters. In addition, the textbooks contain discussions about local hazards, causes and effects of disasters, and the disaster management cycle. Conclusions: The coverage of DRR and the relevant contents in school textbooks reveals that the discourse of natural hazards is important for Iranian authorities, especially in the education system. This study helps decision-makers and practitioners design more effective interventions to prepare children for disasters

    Phylogenetic relationship and genetic differentiation of Populus caspica and Populus alba using cpDNA and ITS noncoding sequences

    Populus caspica Bornm. (section Leuce and subsection Albida), one of the most endangered endemic tree species in the Hyrcanian Forest in Iran, has numerous morphological characteristics that are closely similar to Populus alba; to clarify their taxonomic relatedness and genetic differentiation and thus inform conservation strategies, we used the noncoding regions of chloroplast DNA (cpDNA; trnL-F and trnH-psbA) and the internal transcribed spacer (ITS). Leaf samples were collected from six populations across northern Iran. cpDNA and ITS fragments were amplified by universal primers using the PCR technique and directed sequencing. The results showed that P. caspica is genetically differentiated from P. alba, and two ITS variants were detected within some P. caspica individuals. Conflicts between topologies from ITS and plastid genomes were observed. High differentiation of P. caspica from the other Populus species shown in this study confirmed the diverging taxonomic status of this endangered species. We recommend in situ conservation measures (e.g., protected areas) for at least several populations of this species, especially in the plain regions of the Hyrcanian forest

    Introduction: Children are one of the most vulnerable groups in disasters. Improving students’ knowledge and skills to prepare for disasters can play a major role in children’s health. School as a place to teach children can make a significant contribution to provide the necessary skills. This study aims to identify the effects, strengths and weaknesses of interventions in schools to prepare children for disasters. Methods and analysis: We use Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to develop a protocol for this systematic review. The included studies will report on the results of interventions targeting ‘schoolchildren’ defined as individuals between 4 and under 18 years old studying in schools. Different electronic databases will be used for a comprehensive literature search, including MEDLINE, Web of Science, CINAHL, PsycINFO, Cochrane Register of Controlled Trials and EMBASE to identify the records that match the mentioned inclusion criteria published till December 2020. The main search terms are ‘disaster’, ‘preparedness’, ‘children’ and ‘school’. Four types of data will be extracted from the qualified studies including study characteristics (study design, year of publication and geographical region where the study was conducted), participant characteristics (sample size, age and gender), intervention characteristics (aim of intervention, intervention facilitators and barriers) and intervention outcomes. The quality appraisal of the selected papers will be conducted using Cochrane Collaboration’s Risk of Bias for quantitative studies and Critical Appraisal Skills Programme checklist for qualitative studies. We use a narrative synthesis for this systematic review. The narrative synthesis refers to an approach to systematic reviews which focuses mostly on applying words and texts to summarise and explain findings. Ethics and dissemination: This paper is a part of a Ph.D. thesis of Hamed Seddighi at University of Social welfare and Rehabilitation Sciences with ethics code IR.USWR.REC.1399.008 approved by the Ethics Committee of the above-mentioned university

    Biogeography and phylogenetic relationships of Hyrcanian wild apple using cpDNA and ITS noncoding sequences

    Get PDF
    The Hyrcanian forest of northern Iran is considered one of the potential centres for the evolution and domestication of the genus Malus (Rosaceae). However, the biogeography, phylogenetic position, and taxonomic status of the Hyrcanian wild apples have never been evaluated. In our study, the nucleotide sequences of the internal transcribed spacer (ITS) and the trnH-psbA intergenic spacer region from 14 natural populations were analysed. Phylogenetic analysis based on the ITS and the Maximum-likelihood (ML) tree showed that all Hyrcanian samples were closely related to M. orientalis and M. asiatica and can be placed within section Malus and series Malus. Furthermore, based on a comparison of ITS2 secondary structures, the Hyrcanian samples were identical to M. orientalis and M. sieversii. Biogeographic scenarios constructed using Statistical Dispersal-Vicariance Analysis (S-DIVA) and the Bayesian Binary Method (BBM) indicated that the ancestor of Malus originated during the Eocene, ∼53 million years ago (Ma), and that China played a vital role in the expansion of the range of the genus. The members of Malus colonized the Hyrcanian region from China during the Miocene, ∼22-10 Ma

    This paper reports the floristic survey on the Salaheddinkola forests (Nowshahr). These forests posses high variations in elevation ranges and special physiographic properties, which form the growth platform for most of the typical Hyrcanian forest species. The floristic-physiognomic investigation of the region was performed using field-walk procedure and revealed 237 plant species belonging to 196 genera and 85 families. The important families were Asteraceae, Poaceae, Rosaceae, Lamiaceae and Fabaceae with 23, 20, 14, 13 and 10 species, respectively which represented 33.17 percent of the total species. According to Raunkaiaer method, Cryptophytes (28.7%), Hemicryptophytes (27.5%) and Phanerophytes (22.5%) were the most important structure groups of the local biological spectrum followed by Therophytes (17.7%) and Chamaephytes (3.4%) Chorotypes. According to Zohary, most of the identified species belonged to Euro-Siberian and Pluriregional regions with 79 (33.6%) and 62 (26%) taxa, respectively
